236 PEOCKEDIJfGS OF THE MALACOLOGICAL SOCIETY. 



Some specimens found by Mr. Preston at TJda Pussellawa appear to 

 belong to C. MaricB, wbich was described from Nuwara-Eliya. 

 I now describe three new forms. 



7. Cyathopoma ARTATX7M, n.sp. PI. XVI, Figs. 19, 20. 



Testa dextrorsa, late et perspective umbilicata, depresso-turbinata, 

 apice acntida, periostraco calcareo, deciduo, induta, sub hoc albido- 

 cornea, polita ; anfr. 4^, regulariter accrescentes, spiraliter lirati, sub 

 lente leviter transversim striati, ultimus carinis duabus supra 

 p(iripheriam, unica ad peripheriam, et sex liris magis approximatis sub 

 peripheriam et in umbilico, penultimus duabus carinis ; apertura 

 circularis, peristomate simplice, continue, intus leviter incrassato ; 

 operculum valde concavum, multispirale. Alt. 1"3, lat. 2 mm. 



Sab. — Uda Pussellawa, Ceylon (Preston). 



This minute species is noteworthy for being clothed with a peri- 

 ostracum of a very chalky nature, which, however, appears to be 

 very easily rubbed off, and many specimens only fully exhibit it within 

 the umbilical area. The three upper carinations are sharply edged, 

 while those below the periphery and in the umbilicus are rounded 

 and thread-like. 



8. CrATHOPOMA Prestoisti, n sp. PI. XYI, Figs. 17, 18. 



Texta dextrorsa, elevata, pyramidalis, mediocriter et perspective 

 umbilicata, periostraco brimneo leviter induta, apice obtusula ; 

 anfr. 5, regulariter accrescentes, leviter et obsolete spiraliter lirati, 

 transversim striati, ultimus carinis obsoletis quinque (?), fere Isevis 

 in iimbilico ; sutura bene impressa ; apertura fere circularis, continua, 

 peristomate leviter intus incrassato. Alt. 2, lat. I'Smm. 



Hah. — Uda Pussellawa, Ceylon (Preston). 



In form this species is intermediate between C. Harm and 

 C artatum, with a well-marked suture. The brown periostracum 

 and nearly obsolete carinsB, with the almost smooth umbilical area, 

 are its distinguishing features. 



9. Cyathopoma turbinatum, n.sp. PI. XVI, Figs. 15, 16. 



Testa dextrorsa, depresso-pyramidalis, late et perspective umbilicata, 

 pex'iostraco brunneo levissime induta, apice obtusula ; anfr. 5, celeriter 

 accrescentes, leviter et obsolete spiraliter carinati, in umbilico lirati, 

 xdtimus carinis obsoletis quatuor, duabus supra et unica sub peri- 

 pheriam, unica major ad peripheriam, liris sex (?) in umbilico ; 

 sutura impressa ; apertura circularis. Alt. 2-2, lat. 2*5 mm. 



Hab. — Uda Pussellawa, Ceylon (Preston). 



At first sight this shell might be taken for a variety of C. Sheva- 

 royammi, Beddome, from the Salem district, to which it is very 

 nearly allied. It is, however, smaller, differs in the relative 

 proportion of height to breadth (a specimen I have of C. Sheva- 

 royanum measures: alt. 2"3, lat. 3 ram.), and is of a thinner 

 texture. The carinations above are also not so strongly marked,
